A.itvfcitizenofthe United States, and a resident Y "ofClicag'o, in theconty of Cook and State 'go llinois, have invented certain new anduseful Improveltients in Attachments for Typelvvi'iting Machines; and Ido hereby declare that the following is afull, clear,

'and exact description thereof, reference be- The obJect ofitheinvention is to provide a ytypeivriteir with an attachment formanifielding, whereby a number of carbon copies maybe made with a singleoperation of the machine and whereby said copies may be automaticallyremoved from the platen.

Said gears are so arranged that a rotation of theroll 17 to rewind the ribbon 18 `will produceV a rotation of the roll 24in the same direction to rewind the manifolding lsheet and the gears areso roportioned that the peripheral speed of t e two rolls will besubstantiall vthe same.

` 34 indicates a paper roll rotatively supported in any convenientmanner at the rear of the typewritin machine. As shown in the drawings,sa' roll is shown rotativelyY mounted on standards 35 rising upwardlyfrom a base board 36 supported at the rear of the-machine in anyconvenient manner (not shown). From the paper roll 34 is unwond themanifolding sheet 34. The manifolding strip 34* is fed over the roll 24which is provided with means for attaching said stri toits surface. Y 4

40 i 'cates a plate extending longitudinally of the roll 24 with itsouter surface for part of the cylindric surface of said rell. rod 41 isremovably secured in a slot 41x extending longitudinally of said plate.'As shown said rod has a reduced projection 41|l adapted to engage in ahole or aperture 40" in one end wall Aofthe slot 41%. AThe other end ofsaidrrod projects beyon the end of the roll 24 and is engaged by aswinging ratchet arm 42 pivoted to the end ofsaidv roll and adapted toretain said 1 rod in its associated slot 41". After swingsaid arm 42outwardly to disengageit` :from` the end of the rod41, the rod 41 may bemoved in the direction of its length to I withdraw its reduced end fromthe aperture 40 whereupon said lrod may be removed folding sheet.V

from the slot or groove 41".V By means of this constrl tion, after themanifolding,

strip has been wound upon the platen the required number o`f times, thepart of the manifolding strip intermediate said and the paper roll 34may be clamped 1n the groove 41 by means of the rod 41. A narrowlongitudinal groove 40'l is formed in the surface of the ,plate 40 atthe rear of the rod 41, so that after the manifolding strip has beenconnected to the surface of the roll 24, said strip may be severed byrunning a knife-edge through the groove 40.

The operation of my improved attachment is as follows: Then it isdesired to'produce manifold copies of an original pa er, the forward endof the manifolding s eet 34'L is brought over the roll 24 and down intothe apex of the angle between the forward end of the carbon ribbon andthe surface of the platen 13. (See Fig. 2). The platen is then rotated'in the usual manner which causes the sheet 34 and the carbon ribbon tobe wound about the platen, with the carbon ribbon superposed on top ofthe mani- The platen is rotated as many times as there are co ies to bemade. When making the last rotation of the platen to wind the lastsection of the manifolding sheet on the platen, the original sheet uponwhich the original items are to be written, is fed overl the guide plate15 into the space between the'irolls 16, 16, 16 .of the laten in theusual manner, said sheet thus yin on to of the outer section of thecarbon rib on. T e writing isthen made upon the original sheet in theusual manner. The length of the circumference' of the platen 13 and oflaten the roll 24, which is the same, is equal to the length from thevtop to the bottom of the original sheet.A Thus eachV winding of themanifolding sheet on the 'platen represents the length from top tobottom of one ofthe manifolding copies when the sheet is severed intothe `several copies which comprise its length. After the original hasbeen written the rod 41 is withdrawn endwise from the roll 24 andthemanifolding strip 34a is clamped b said rod in the cove 41* inthesurface o said roll. The roll 24 duringthe winding ofthe manifoldingstrip and carbon ribbon upon the platen and during the writing upon theoriginal has been rotat-in forwardly with the ribbon ro'lltoward t eplaten and at a circumferential speed equal to the speed of the platen.4The roll 24 has a predetermined anlg'ular and spaced relation to thelaten suc that the end 18"L of the carbon ri bon attached to the platenis distant from the groove 40 in the plate 40 of said roll 24 measuredby a strip being wound upon the platen and unwound from said roll 24. orvice versa, a space Iequal to the length of the original, winch, asbefore stated, is equal to the length of the circumference ofthe platen,and also to `the length of the circumference of the roll A blade orknife-edgev is then used to sever the manifoldingstrip in the plane ofthe groove liOl whereupon sections of said stri of like length and eachequal to the lengtli of the original and containing a carbon copythereof will drop from the roll 24 and may be gatheredup anddistributed.

While in describing my invention I have` referred to certain details ofmechanical construction and arrangement, manifestly these may be changedin various ways without departing from the spirit of my invention and Ido not wish to be limited thereby except as ointed out in the appendedclaims.
